电极对天线增大通信距离的方法研究

内容简介：首先分析了水下电流场通信的原理，给出了电极对天线接收信号电压的表达式。针对水下通信距离近的问题提出了增加通信距离的方法，包括定向天线法、介质盘法和改变传感器的形状。根据以上方法的要求制作了不同类型的电极对天线，并在实验池中对上述方法进行试验测试分析，测试结果验证了以上方法的可行性。

Abstract：First ,the paper has analyzed the principle of underwater current field and provided the received voltage of E-field sensor . To the question of short communication distance , some methods of increasing communication distance are raised ,including directional antenna ,medium plate and changing sensor's shape .Different kinds of sensors are made depen-ding on above methods ,and testified in experimental pool .The result tesfifies the possibility of above methods .
